Kooks
Custom Headers set the standard for the header and exhaust industry.
Kooks kits come with everything needed to complete the install. All of
Kooks products are hand made in the USA using premium stainless steel.The
OEM exhaust that comes from the factory on your S550 just doesn’t cut
it. Factory exhaust is restrictive, quiet and unsightly. Kooks recently
released their 3" Stainless Steel Cat-Back Exhaust System with Black
Tips for your 2015-17 GT Mustang with Kooks Long Tube Headers.
With mandrel bent bends and a wide 3” diameter, this exhaust system
will unleash the beast within your S550. Adding horsepower and torque,
this system includes an x-pipe, intermediate pipes and oval race
mufflers with 4” polished slash cut exhaust tips.
